Erich Fromm on Existence and Experiencing God

"Gentlemen, as a physicist who has dedicated his entire life to the sober pursuit of science, to the exploration of matter, I am certainly free from the suspicion of being taken for an idle dreamer. And so, after my investigations into the atom, I declare this: There is no such thing as matter in itself. All matter comes into being and persists only through a force—a force that sets the particles of the atom into vibration and binds them together as the minutest solar system of the cosmos. Yet, since neither an intelligent nor an eternal force exists within the vast expanse of the universe—for humanity has failed to devise the long-sought perpetuum mobile—we must posit behind this force a conscious, intelligent spirit. This spirit is the primal source of all matter. It is not the visible, transient matter that constitutes the real, the true, the actual—for without the spirit, matter would not exist at all—but rather the invisible, immortal spirit that is the ultimate truth! Yet, since spirit alone cannot exist either, and every spirit belongs to a being, we are compelled to assume the existence of spiritual beings. And since these beings cannot arise from themselves but must be created, I do not shy away from naming this mysterious creator as all civilized peoples of the earth have called Him in earlier millennia: God! Thus, the physicist, tasked with the study of matter, steps from the realm of the material into the realm of the spirit. And with that, our work concludes, and we must entrust our inquiry to the hands of philosophy." Max Planck
